Many researches have been carried out on the development of high-capacity electrode
materials to enhance the battery performance. Lithium ion battery offer high-energy
capacity and good electrochemical stability but have safety issues. Furthermore, the
usage of polyvinylidene fluoride (PVDF) as binder material for Li-ion battery electrodes
is costly and environmentally unfriendly. The purposes of this research is to prepare
anode using different composition of chitosan-based binder, characterize the anode
using XRD and SEM and determine the electrochemical properties by measuring the
OCV and charge-discharged characteristic. The solid polymer electrolyte (Spe) was
prepared in the form of thin film then underwent EIS to verify the conductivity. The
highest conductivity was used to fabricate the battery. The electrode was prepared in
form of pellet and scanned using XRD at angle between 10 o to 90 o . For electrode
morphology analysis, SEM was used. The electrode was observed at the magnification
of 500x and 1500x.
